Abstract (AB)Three species of armyworm, Mythimna curvula, Simplicia pannalis and Aethis ignava, have been collected from young sugar cane ratoons following a heavy attack in many fields after mechanical harvesting. Severe damage results in complete defoliation. M. curvula feeds on cane foliage and S. pannalis and A. ignava feed on cane trash. Preliminary observations indicate that there is no appreciable effect of armyworm damage on yield, but these need confirmation. Thiodicarb, which at 1.5 g a.i./l gave better control than azinphos methyl at 0.4 g a.i./l, has a stomach action with limited contact action. It is therefore better adapted within an integrated pest management strategy. The tachinid fly, 'Alsomyia' anomala (generic name uncertain) represented 95 per cent of the number of parasites. Average parasitism was 20 per cent.
